I'm having a tough time sizing the buttons on a toolbar. They're too large, and I can't figure out how to make them smaller. I have tried changing the ButtonHeight property, but it keeps resetting to 450.1418. The ButtonWidth property is also stuck at 464.8819. Grabbing the handle at the bottom of the toolbar with the mouse doesn't work either.

I've got 2 questions:
1. Are the button sizes determined by the images that are used?
2. Anybody know how to reduce the toolbar button size?

Thanks for the help.
